That's because the clang build uses gcc, not clang. The [sequence of commands](https://travis-ci.org/davidgiven/ack/jobs/301659553) is\r\n\r\n```\r\n$ export CC=clang\r\n$ clang --version\r\n$ make PREFIX=/tmp/acki +ack\r\n```\r\n\r\nbut the Makefile's `CC = gcc` takes precedence over the environment's `CC=clang`."}}
